55V – 3A Half-Bridge Power Driver Module

This Half-bridge module provides current measurement and regulation features for various loads. The module can be used to drive solenoids, Relays, Valves, DC-DC converters, Brushed DC motors, or other loads.  It can operate from a 5V to 55V supply voltage and can deliver up to 3A of output current (depending on ambient temperature). Cycle-by-cycle current regulation, current limiting is adjustable using PR1 trimmer pot. Internal diagnostic and protection features include open-load detection, over-current protection (OCP), under-voltage lockout (UVLO), and thermal shutdown. The overcurrent limit is set to 3A and the retry time is 1.6mS. Solenoids can be controlled ON/OFF using Jumper J1. Use the PWM signal at the input pin for DC motor speed control.
